Icescape Ltd v Ice-World International BV & Ors [2018] EWCA Civ 2219 (10 October 2018)

Icescape Ltd v Ice-World International BV & Ors [2018] EWCA Civ 2219 (10 October 2018)

The patent was not entitled to priority because the features of multiple elements, their arrangement, and coupling members were not disclosed, directly or implicitly, in the priority document. Therefore, the patent was invalid. However, if the patent had been valid, Icescape's system would have infringed under the doctrine of equivalents, as the inventive core (foldable joint member) was present and the differences were immaterial.

Procedural Posture

Patent Infringement and Validity Appeal / Appeal From High Court (patents Court) to Court of Appeal

Legal Issues

  1. 1 Whether the patent is entitled to priority from the priority document
  2. 2 Whether the patent is valid
  3. 3 Whether Icescape's system infringes the patent under normal interpretation or the doctrine of equivalents

Ratio Decidendi

The patent was not entitled to priority because the features of multiple elements, their arrangement, and coupling members were not disclosed, directly or implicitly, in the priority document. Therefore, the patent was invalid. However, if the patent had been valid, Icescape's system would have infringed under the doctrine of equivalents, as the inventive core (foldable joint member) was present and the differences were immaterial.

Court Disposition

Appeal dismissed; patent held invalid for lack of priority entitlement.

Orders
